### This week's updates

**Updates**
- **Marketplace Handle Availability**: The [`GET /2/marketplace/handles/{handle}/availability`](/x-api/marketplace/get-marketplace-handle-availability) endpoint now returns a `product_tier` field, letting you see which product tier (for example, `premium`) a handle is associated with. Request it via the `marketplace.fields` parameter.

**Removals**
- **Chat conversation lookup**: The `GET /2/chat/conversations/{id}` endpoint has been removed from the X API v2. Use the remaining [Chat endpoints](/x-api/chat/get-chat-conversations) to list conversations and manage messages.
</Update>

### Change to DM Events Behavior
Today, we made a change to X API V2 DM Events behavior. With the new change participant_ids array will only be included for ParticipantsJoin and ParticipantsLeave events, and it will list only the participants who joined or left at the time of the event. The MessageCreate event will no longer include the participant_ids array. Learn more [here](https://devcommunity.x.com/t/upcoming-change-to-x-api-dm-events-endpoints-behavior/241841).
